transition from whatever on Preview to Program, anything that's an Upstream key is going to be
transitioned with it.
9.1. Luma Key
DIP to White (fade out):
DIP to Black (fade out):
Key Source ≠ Fill Source
Key Source = Fill Source

14
Luma keys provide a way to composite a Text clip over a background clip based on the luminance levels
in the video. Turn on the Luma Key, a color from the key source will be removed, revealing another
background image behind it.
Switching a video with background to PVW window, and turn on the Luma Key. Press the menu knob to
enter the setting interface. Under Luma Key seb-menu, user can assign the fill and key source from
various options including Black/ Color Bar/ Color1/ Color 2/ SDI1/ SDI2/ HDMI3/ HDMI4/ Image (import
from USB disk). Configure and adjust the Key parameters including Clip/Gain/mask to achieve
the effect needed.
Press ON AIR button, the ON AIR button will be on, and the Key effect will show on PGM.
LUMA button ON: Luma key shows on PVW
ON AIR button ON: Luma Key available on PGM
LUMA and ON AIR button both ON: Luma Key available on both PVW and PGM. Corresponding status in
menu is <KEY & ON AIR>
Luma key menu interface and parameter setting as below:
Clip: Adjust the threshold at which the key cuts its hole. When decrease the clip degree, more of the
background will appear. If the background video is completely black then the clip value is too low.
Gain: Adjusts the performance of the chroma key in light or white areas. Apply more Key Gain if the light
areas are becoming too transparent.
Invert Key: Inverts the key signal.

used in many fields to remove a background from the subject of a photo or video, particularly
the newscasting, motion picture, and video game industries.
User can configure the effect of Chroma Key, including the key source, Key color, Clip, Gain, key Fetch
and mask, etc. in the menu page.
Press the ON AIR button next to the CHROMA button to enable the KEY on PGM.
CHROMA button ON: Chroma key shows on PVW.
